The rebuild command "RE" no longer works on Draftsight 2016 X64 SP2.

it used to work just fine in  Draftsight 2015 X64.

I would type "re" and the drawing would REBUILD no problem. after i moved to the 2016 build the "re" command stopped working and you HAVE to type the whole word  REBUILD for it to work.

WHY WHY WHY would this be removed. How does removing features improve the product?

Is there a way to fix this?
